Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Possibilities for maximizing the tritium breeding ratio (TBR) and for minimizing the major radius of the Next European Torus (NET) fusion device are investigated using the nucleonic optimization code SWAN. It is found that a NET like device can be designed to be tritium self-sufficient even when tritium breeding is restricted to the outboard blanket, while enabling a 25 cm reduction in the major radius of the device, Additional 20 cm major radius reduction is expected from replacing the conventional steel-water inboard shield by an optimized shield based on a tungsten-copper composite material and titanium-hydride.
